Actually max payload is all the truck is rated to carry, and all the BRAKES are designed to STOP. No matter where the weight is. The brakes are only designed to stop the GVWR of the truck.
BTW. at max GVWR. The brakes are not designed to stop ANY of the trailer.
Fairly certain that the axle rating takes into account the suspension, wheels, tires AND braking ability for the axle.
Furthermore, trucks are designed to be able to handle a certain amount of trailer load without brakes. On my Ram its either 3500 or 5000 lbs of trailer are allowed without requiring brakes (I'll have to check my manual, too lazy to go outside now though). Again... my Ram's braking system doesn't know if that weight is in the bed or on a trailer. It will just stop the load.
